2.4 Adjustment to Closing Payment.

(a) The Company shall have delivered to the Buyer a balance sheet of the Company, updated from and after the Balance Sheet Date (the “Estimated Closing Balance Sheet”), which the Company shall certify as being a good faith estimate of the balance sheet of the Company as of the Closing Date.

(b) In the event that the Company Stockholder Equity as set forth in the Estimated Closing Balance Sheet is less than or greater than the Company Stockholder Equity Amount, the Buyer shall adjust the Closing Payment to be delivered to the Company Stockholder at Closing (a “Closing Payment Adjustment”) as follows:

(i) if Company Stockholder Equity is greater than the Company Stockholder Equity Amount, the Closing Payment shall be increased dollar by dollar by such difference; and

(ii) if Company Stockholder Equity is less than the Company Stockholder Equity Amount, the Closing Payment shall be decreased dollar for dollar by such difference.

(c) Within sixty (60) days after the Closing Date, the Buyer and the Company Stockholder shall agree to a statement of work (the “Statement of Work”) pursuant to which an audit firm will audit on a timely basis the Company’s financial statements, books and records and prepare and deliver to the Buyer and the Company Stockholder a Selected Accountant’s Certificate (as defined below). Such audit will be conducted in conformance with the provisions of Section 2.7 and the Selected Accountants’ Certificate shall be prepared in conformance with the provisions of Section 2.7. The Buyer shall deliver the Statement of Work to each audit firm listed on Schedule 2.4(c) hereto and request a proposal from each. The Buyer and the Company Stockholder shall select from among the proposals the lowest bidding firm which has indicated that it can accomplish the requirements of the Statement of Work in the time frame indicated therein (the “Selected Accountants”). The Selected Accountants shall provide a signed certificate (the “Selected Accountants’ Certificate”) certifying the Selected Accountants’ determination of the Company Stockholder Equity as of the Closing Date, and identifying any adjustments to the Company Stockholder Equity as reflected on the Estimated Closing Balance Sheet, which determination will become final and binding upon the Parties unless, within thirty (30) days following delivery of the Selected Accountants’ Certificate, the Buyer or the Company Stockholder objects in the manner set forth below. If the Final Company Stockholder Equity (as defined below) is greater than the Company Stockholder Equity as reflected on the Estimated Closing Balance Sheet, the Buyer shall, within three (3) business days, pay to the Company Stockholder, the amount of such difference. If the Final Company Stockholder Equity is less than the Company Stockholder Equity as reflected on the Estimated Closing Balance Sheet, the amount of such difference shall, within three (3) business days, be paid to the Buyer from the Escrow Fund. As used herein, the term “Final Company Stockholder Equity” shall mean the Company Stockholder Equity reflected in the Selected Accountants’ Certificate if uncontested, or the amount finally determined by negotiation of the Parties or by the Neutral Auditor, as provided below.

(d) The cost of retaining the Selected Accountants to conduct such review and to prepare such certificate shall be borne by equally by the Company Stockholder and the Buyer. The Buyer shall permit the Company Stockholder (who, for the purposes of this Section 2.4 shall include his representatives) and, if applicable, the Neutral Auditor (as defined below) access to

such work papers and all other applicable documents of the Company relating to the preparation of the Selected Accountants’ Certificate as may be reasonably necessary to permit the Buyer, the Neutral Auditor and the Company Stockholder to review in detail the manner in which the Selected Accountants’ Certificate was prepared. If the Buyer or the Company Stockholder objects to any item on the Selected Accountants’ Certificate, the Buyer or the Company Stockholder shall notify the Selected Accountants in writing of such objection within thirty (30) days after the Buyer’s and the Company Stockholder’s receipt of the Selected Accountants’ Certificate (such notice setting forth in reasonable detail the basis for such objection). The Buyer and the Company Stockholder shall thereafter negotiate in good faith to resolve any such objections. If the Buyer and the Company Stockholder are unable to resolve any such disagreements within fifteen (15) days of the Buyer’s (or the Company Stockholder’s) receipt of the Company Stockholder’s (or the Buyer’s) objections, the Buyer and the Company Stockholder shall jointly retain Ernst & Young LLP or another mutually agreed to national accounting firm (the “Neutral Auditor”) to resolve any remaining disagreements. At the time of the Neutral Auditor’s selection, each of the Buyer and the Company Stockholder shall represent and warrant that, at such time, it does not have and has not had any material relationship with the Neutral Auditor in any capacity, including without limitation, as an auditor, consultant or teaming partner. Each Party agrees to execute, if requested by the Neutral Auditor, a reasonable engagement letter with the Neutral Auditor. The Neutral Auditor shall determine only those issues in dispute at the end of the resolution period and the Neutral Auditor’s determination shall be based upon and consistent with the terms and conditions of this Agreement. The determination by the Neutral Auditor shall be based solely on presentations with respect to such disputed items by the Buyer and the Company Stockholder to the Neutral Auditor and not on the Neutral Auditor’s independent review. Each of the Buyer and the Company Stockholder shall use its reasonable best efforts to make its presentation as promptly as practicable following submission to the Neutral Auditor of the disputed items, and each such Party shall be entitled, as part of its presentation, to respond to the presentation of the other Party and any questions and requests of the Neutral Auditor. In deciding any matter, the Neutral Auditor (i) shall be bound by the provisions of this Section 2.4(d) and (ii) may not assign a value to any item greater than the greatest value for such item claimed by either the Buyer or the Company Stockholder or less than the smallest value for such item claimed by the Buyer or the Company Stockholder. The Buyer and the Company Stockholder shall direct the Neutral Auditor to render a determination within forty-five (45) days of its retention (which retention shall be made no later than five (5) business days after the 15-day period), or as soon thereafter as possible, and the Buyer and the Company Stockholder shall use commercially reasonable efforts to cause the Neutral Auditor to resolve all disagreements over individual line items as soon as possible. The Neutral Auditor shall consider only those items and amounts in the Selected Accountants’ Certificate which the Buyer and the Company Stockholder are unable to resolve. The determination of the Neutral Auditor shall be final, conclusive, non-appealable and binding upon the Buyer and the Company Stockholder for all purposes hereunder, provided that such determination may be reviewed, corrected or set aside by a court of competent jurisdiction but only upon a finding that the Neutral Auditor committed manifest error with respect to its determination. All fees and expenses (including reasonable attorneys’ fees and expenses and fees and expenses of the Neutral Auditor) incurred in connection with any dispute over the Selected Accountants’ Certificate shall be borne by the

Parties based on the percentage which the portion of the contested amount not awarded to each Party bears to the amount actually contested by such Party.

2.5 No Further Rights. The Purchase Price paid for the Company Stock in accordance with the terms hereof shall be deemed to have been paid in full satisfaction of all rights pertaining to such Company Stock.

2.6 Taking of Necessary Action; Further Action. If, at any time after the Closing, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest the Buyer with full right, title and possession to all assets, property, rights, privileges, powers and franchises of the Company, the Company Stockholder agrees to take, and will take, all such lawful and necessary action required to so do, so long as such action is not inconsistent with this Agreement. If, at any time after the Closing, any further action is necessary or desirable to terminate any personal guaranties made by the Company Stockholder in connection with any Company obligations or liabilities or to remove the Company Stockholder as a trustee under any Employee Benefit Plan, the Buyer and the Company agree to take, and will take, all such lawful and necessary action reasonably requested by the Company Stockholder.

2.7 Accounting Terms. Except as otherwise expressly provided herein or in the Schedules hereto including without limitation, the definition of Company Stockholder Equity in Article I, all accounting terms used in this Agreement shall be interpreted, and all financial statements, Schedules, certificates and reports as to financial matters required to be delivered hereunder shall be prepared, in accordance with generally accepted accounting principles (“GAAP”), consistently applied by Company; provided, however, that in the event that any accounting principles consistently applied by Company are not in accordance with GAAP, then the Selected Accountants shall use accounting principles that conform with GAAP and which are customarily applied by firms in the government information technology services industry. Notwithstanding the foregoing, the Interim Financials shall not be required to contain (a) notes otherwise required under GAAP and (b) shall be subject to normal year-end adjustments. Furthermore, subject to the above provisions, the parties understand and acknowledge that there are elements to GAAP that are subject to interpretation and that there may be more than one acceptable method of handling a particular item under GAAP.

2.8 Form of Payments. All payments made pursuant to this Agreement shall be made by delivery to the recipient by bank wire transfer, the required amount (in immediately available funds) in an account of the recipient, which account shall be designated by the recipient in writing at least three (3) business days prior to the date of the required payment.

5.3 Unpaid Taxes; Refunds. The Company Stockholder covenants and agrees to reimburse promptly the Buyer for any amount by which the Company’s liability for unpaid Taxes, if any, for all periods or portions thereof ending on or before the Closing Date exceeds the

5.4 Tax Returns.

(a) The Company Stockholder shall prepare or cause to be prepared and timely file, by not later than January 31, 2005, and the Company and the Buyer shall cooperate with the Company Stockholder in the preparation and timely filing of, all Tax Returns required to be filed by or on behalf of the Company after the Closing Date which apply to periods prior to the end of the Closing Date (the “Pre-closing Returns”).

The Company shall timely pay any Taxes shown as due by the Company on the Tax Returns described in this Section 5.4.

(b) If any Tax shown as due on any such Tax Return referred to in (a) above is required to be borne by the Company Stockholder (taking into account indemnification obligations hereunder and adjustments to the Purchase Price) or affects taxable income reportable by the Company Stockholder by reason of his former ownership of the Company Stock, such Tax Return shall be prepared in a manner consistent with the prior practice of the Company unless otherwise required by applicable Tax laws; a draft of each such Tax Return shall be provided to the Company for review and approval not later than December 31, 2004 (or, if required to be filed within thirty (30) days of the Closing, as soon as possible following the Closing); and the Company and the Buyer shall have the right to review and approve such Tax Return prior to the filing of such Tax Return (which approval shall not be unreasonably withheld or delayed). The Company and the Buyer shall prepare or cause to be prepared all Tax Returns of the Company for periods commencing after the Closing Date and shall be responsible for paying any Taxes shown as due on such Tax Returns.

(c) The Parties shall, unless prohibited by applicable law, cause the taxable period of the Company to end as of 11:59 p.m. local time on the Closing Date. For the avoidance of doubt, the Parties hereto agree that the taxable year of the Company, as a subchapter S corporation, shall terminate and end at the end of the Closing Date for federal income tax purposes (and to the extent applicable, for state and local tax purposes as well), and that all items of income, gain, deduction, or loss recognized after the Closing Date shall be included by the Company and the Buyer in the Buyer’s consolidated federal income Tax Return (and to the extent applicable, in the Buyer’s Tax Return for state and local tax purposes as well).

5.5 Cooperation on Tax Matters.

(a) The Buyer, the Company and the Company Stockholder (at no expense to the Company Stockholder) shall cooperate fully, as and to the extent reasonably requested by the other Parties, in connection with the filing of Tax Returns pursuant to this Section and any audit, litigation or other proceeding with respect to Taxes. Such cooperation shall include the Buyer and the Company providing to the Company Stockholder the same information as provided to the Selected Accountants under Section 2.4(c) at the same time that the Buyer or the Company provides such information to the Selected Accountants, the retention and (upon the other Parties’ request) the provision of records and information that are reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The Company agrees (i) to retain all books and records with respect to Tax matters pertinent to the Company relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations (and, to the extent notified by the Buyer or the Company Stockholder, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any taxing authority, and (ii) to give the other Parties reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other Parties so request, the Company shall allow the other Parties to take possession of such books and records.

The Buyer shall, upon request by Company Stockholder and at his sole expense, cooperate in the preparation of and submission to the proper taxing authority of any such amended Tax Return which is required to cause such Tax Return to be consistent with adjustments to the Tax Returns of the Company for any other taxable period proposed by any taxing authority, or to give effect to an allowable loss carryback or carryover from a taxable period of the Company ending on or before the Closing Date.

assessment, or adjustment relating to the Company, or the Company Stockholder with respect to the Company, which may give rise to liability of another Party hereto, shall promptly notify the Buyer and the Company Stockholder within ten (10) business days of the receipt of such notice. The Parties each agree to consult with and to keep the other Parties hereto informed on a regular basis regarding the status of any Tax audit or proceeding to the extent that such audit or proceeding could affect a liability of such other Parties (including indemnity obligations hereunder). The Company Stockholder shall have the right to represent the Company’s interests in any Tax audit or administrative or judicial proceeding and to employ counsel of the Company Stockholder’s choice, but reasonably satisfactory to the Buyer, at their expense, but only to the extent such audit or other proceeding pertains to taxable periods ending on or before the Closing Date. The Buyer shall have the right to participate in such proceeding at its own expense, and shall be entitled to control the disposition of any issue involved in such proceeding which does not affect a potential liability of the Company Stockholder. The Buyer and the Company Stockholder shall be entitled to represent their own interests in light of their responsibilities (including indemnity obligations) for the related Taxes, at their own expense, in any audit or administrative or judicial proceedings involving a taxable period that includes but does not end on the Closing Date. Notwithstanding the foregoing, the Company Stockholder shall not agree to any settlement for any taxable period that would effect Tax liabilities of the Buyer or the Company for any taxable period beginning on or after the Closing Date without prior written consent of the Buyer.

(d) The Buyer and the Company Stockholder shall jointly make a timely election provided for by Section 338(h)(10) of the Code and Section 1.338(h)(10) of the Treasury regulations (and any comparable election under state or local laws) (collectively, the “Election”) with respect to the acquisition of the Company Stock. The Purchase Price shall be allocated among the assets of the Company based upon the fair market value of the assets of the Company at the time of Closing for purposes of completing all forms of any nature necessary to effectuate the Election (including, but not limited to, Internal Revenue Service Form 8023, Corporate Qualified Stock Purchase, Form 8883 (Asset Allocation Statement) and any similar forms under applicable state or local law) (the “Section 338 Forms”) in accordance with applicable U.S. Treasury regulations. Such allocation shall be agreed upon by the Buyer and the Company Stockholder as of the Closing Date and shall be set forth on Exhibit C attached hereto and made a part hereof. Based on such allocation, the Buyer and the Company Stockholder shall jointly prepare the Section 338 Forms and the Buyer and the Company shall execute and deliver the Section 338 Forms to one another for filing. The Company and the Buyer shall duly and timely file the Section 338 Forms in accordance with applicable tax laws and in accordance with this Agreement. The Company and the Buyer shall report the acquisition by the Buyer of the Company Stock pursuant to this Agreement consistent with the Elections and shall take no position contrary thereto or inconsistent therewith in any Tax Return, any discussion with or proceeding before any taxing authority, or otherwise. The Buyer agrees to provide the Company Stockholder within thirty (30) days of the Closing Date written instructions in accordance with applicable law as to what is necessary to file a timely, valid Election. The Company Stockholder and the Company agree to comply with such reasonable instructions.

In the event the parties are unable to agree as to the allocations referred to above, the parties shall appoint an independent accountant to resolve such dispute whose costs shall be borne equally by such parties.

(e) The Buyer and the Company Stockholder further agree, upon request, to use their reasonable efforts (without expense to the Company Stockholder) to obtain any certificate or other document from any Governmental Entity or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including, without limitation, with respect to the transactions contemplated hereby).

(f) The Buyer shall pay the Company Stockholder as additional consideration an amount equal to fifty percent (50%) of the additional state and federal taxes incurred directly by the Company Stockholder and the Company solely from the Election (including any 1374 Tax), up to an aggregate payment amount of One Million Dollars ($1,000,000) (the “Tax Amount”). Any such amounts incurred by the Company Stockholder shall be calculated by the Company Stockholder and submitted to the Buyer for its approval along with supporting work papers. Any such amounts incurred by the Company shall be calculated by the Buyer and submitted to the Company Stockholder for his approval along with supporting work papers. In each case, such approval shall not be unreasonably withheld. If the Parties are unable to agree as to the Tax Amount, such dispute shall be resolved by an independent accountant chosen by the Parties whose costs shall be borne equally by the Parties.

(g) The Buyer covenants that it will not and will not cause or permit the Company or any Affiliate of the Buyer to (i) take any action on the Closing Date other than in the Ordinary Course of Business, including, without limitation, the distribution of any dividend or the effectuation of any redemption which would result in any tax liability to the Company Stockholder, or (ii) make any election or deemed election under Section 338 of the Code on the Closing Date other then the Election or amend any Tax Return of the Company on the Closing Date.

5.6 Director and Officer Indemnification.

(a) The Buyer agrees that it shall cause, for a period of six (6) years after the Closing, all rights to indemnification existing immediately prior to the Closing in favor of the current and former directors (both in their capacity as directors and officers of the Company) of the Company at or prior to the Closing and the officers of the Company listed in Section 5.6(a) of the Disclosure Letter (“Indemnified Employees”) as provided for in the Company’s Bylaws as of the date hereof to continue (without amendment or modification in any way unless required by law or regulation) in full force. Subject to the foregoing, the Buyer may, from and after the Closing, cause the Company to merge, dissolve or reorganize.

(b) This Section 5.6 shall be binding on all successors and assigns of the Company and the Buyer. In the event that the Buyer or the Company or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the

continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then and in each such case, proper provision shall be made so that such successors and assigns shall assume all obligations set forth in this Section 5.6. The provisions of this Section 5.6 are intended to be for the benefit of, and shall be enforceable by, each Indemnified Employee, his or her heirs, or his or her representatives or assigns.

5.7 Excluded Assets. The Buyer and the Company Stockholder acknowledge and agree that the assets set forth in Section 5.7 of the Disclosure Letter may be transferred by the Company to the Company Stockholder at or prior to the Closing.

5.8 Books and Records. Each Party agrees that it will reasonably cooperate with and make available (or cause to be made available) to the other Party, during normal business hours, all books and records, information and employees (without substantial disruption of employment) retained, remaining in existence or continuing to be employed after the Closing Date which are necessary or useful in connection with any Tax inquiry, audit, or dispute, any litigation or investigation or any other matter requiring any such books and records, information or employees for any reasonable business purpose (a “Permitted Use”). The Party requesting any such books and records, information or employees shall bear all of the out-of-pocket costs and expenses reasonably incurred in connection with providing such books and records, information or employees. All information received pursuant to this Section 5.8 shall be kept confidential pursuant to Section 8.1 (which shall continue to apply to this extent following the Closing Date) by the Party receiving it, except to the extent that disclosure is reasonably necessary in connection with any Permitted Use.

5.9 Employees. The Buyer’s present intention is to retain the Company’s employees at positions and salaries substantially commensurate with their current positions, and to retain the Company’s current level of benefits without making any material adverse change thereto. The Buyer shall use commercially reasonable efforts to provide employees with credit for past service with the Company with respect to any new or amended benefits. The Buyer shall cause the Company to accrue employee bonuses through December 31, 2004 (the “2004 Bonuses”) in the Ordinary Course of Business and to pay the 2004 Bonuses to the employees in the Ordinary Course of Business; provided that the Company shall not be required to pay 2004 Bonuses in excess of $750,000 and shall not include any amounts to be paid to the Company Stockholder or the Former Stockholder. Immediately after the Closing, the Buyer shall provide the Company employees the Buyer stock options set forth on Exhibit J subject to an employee’s execution of the Agreement Concerning Confidential Information and Other Property.

5.10 Identified A/R.

Neither the Buyer nor the Company shall compromise the amount or timing of payment of

the Identified A/R without the prior consent of the Company Stockholder, such consent not to be unreasonably withheld or delayed. If the Buyer or the Company shall determine to compromise any portion of the Identified A/R without the Company Stockholder’s prior consent, then a corresponding amount shall be released from the A/R Escrow and such compromise shall be deemed a Payment Event.

5.11 Certain Assets. Promptly after the Closing, the Buyer shall in good faith determine whether the software product AccuCode (i) has material value to the business of the Company, (ii) was developed pursuant to Government Contracts of the Company or independently by the Company and (iii) if transferred out of the Company prior to the Closing, would have materially adversely affected the Purchase Price. The Buyer may make whatever investigation that it deems reasonable and necessary with respect to making the determination referred to in the preceding sentence, including, without limitation, discussing AccuCode with the Former Stockholder. In the event that the Buyer determines that AccuCode does not have material value to the business of the Company, was not developed pursuant to Government Contracts of the Company and if transferred out of the Company prior to the Closing, would not have materially adversely afffected the Purchase Price, the Buyer shall immediately cause the Company to transfer all rights in AccuCode to the Former Stockholder without payment by the Former Stockholder pursuant to documentation reasonably acceptable to the Buyer and the Former Stockholder.

(i) Flow of Funds Memorandum. The Company and the Company Stockholder shall have executed and delivered the flow of funds memorandum, in substantially the form set forth as Exhibit I (the “Flow of Funds Memorandum”).

(j) Payments Under Retention Agreements.

(i) Pursuant to the terms of the Retention Agreements, the Company (upon receipt of funds from Buyer) shall pay each Exhibit H Employee, the amount in cash appearing next to such employee’s name on Exhibit H attached hereto (a “Initial Employee Bonus Payment” and collectively, the “Initial Employee Bonus Payments”); provided, however, in no event shall the aggregate amount of the Initial Employee Payments exceed One Million Five Hundred Thousand Dollars ($1,500,000).

(ii) If the Company meets or exceeds the revenue target of Fifty Million Dollars ($50,000,000) for calendar year 2004 (the “2004 Revenue Target”), each Exhibit H Employee is eligible to receive an additional bonus payment to be paid on March 31, 2005 under the terms of the Retention Agreements in the amount appearing next to such employee’s name in Exhibit H (collectively the “March 2005 Performance Bonus Payments”); provided, however, in no event shall the aggregate amount of the March 2005 Performance Bonus Payments exceed Five Hundred Thousand Dollars ($500,000). In the event that the Company meets or exceeds the 2004 Revenue Target, any portion of the March 2005 Performance Bonus Payments not made to an employee either because such employee is not actively employed by the Company on March 31, 2005, or for another reason contemplated by the Retention Agreements, such unpaid amounts shall either be paid to another employee of the Company designated in writing

by the Company Stockholder, or to the Company Stockholder as agreed to by the Company Stockholder and the Buyer.

(iii) If the Company meets or exceeds the revenue target of Fifty Million Dollars ($50,000,000) for calendar year 2005 (the “2005 Revenue Target”), each Exhibit H Employees is also eligible to receive an additional bonus payment to be paid on March 31, 2006 under the terms of the Retention Agreements (collectively the “March 2006 Performance Bonus Payments”) calculated as follows: if the 2005 Revenue Figure is greater than Fifty Million Dollars ($50,000,000) but less than Fifty Seven Million Dollars ($57,000,000) then each such Exhibit H Employee shall receive the March 2006 Performance Bonus Payment set forth opposite his or her name on Exhibit H multiplied by a fraction, the numeration of which is the 2005 Revenue Figure minus Fifty Million Dollars ($50,000,000) and the denominator of which is Seven Million Dollars (7,000,000). For example, if the 2005 Revenue Figure is Fifty Three Million Five Hundred Thousand Dollars ($53,500,000), then the aggregate March 2006 Performance Bonus Payments would equal Five Hundred Thousand Dollars ($500,000). In no event shall the aggregate amount of the March 2006 Performance Bonus Payments exceed One Million Dollars ($1,000,000). In the event that the Company meets or exceeds the 2005 Revenue Target, any portion of the March 2006 Performance Bonus Payments not made to an employee either because such employee is not actively employed by the Company on March 31, 2006, or for another reason contemplated by the Retention Agreements, such unpaid amounts shall either be paid to another employee of the Company designated in writing by the Company Stockholder, or to the Company Stockholder as agreed to by the Company Stockholder and the Buyer.

(iv) Beginning on the Closing Date and continuing until December 31, 2005, the Buyer shall ensure that the Company is managed in the Ordinary Course of Business, and shall not take any action intended to, or that could reasonably be expected to, result in a reduction in the business or revenues of the Company, unless such action is permitted in accordance with Section 6.1(j)(v) below.

If Buyer

breaches its obligations under this subsection (iv), then the March 2005 Performance Bonus Payments and March 2006 Performance Bonus Payments shall be paid in the amounts set forth on Exhibit H and pursuant to the terms of this Section 6.1(j) regardless of whether the Company meets the target revenues set forth above.

Notwithstanding the foregoing, in the event of a dispute as to whether the Modification has occurred, such dispute shall be settled in accordance with Section 7.6(b), and the funds in the Contract Escrow shall remain in escrow and not be released to any Party until resolution of the dispute.

(d) If the Indemnifying Party chooses to defend or participate in the defense of any Asserted Liability as provided hereunder, the Indemnified Party shall make available to the Indemnifying Party any books, records or other documents within its control that are necessary or appropriate for such defense and shall otherwise cooperate in the defense of such Asserted Liability.

(b) The Buyer will indemnify and hold the Company Stockholder harmless from any payment alleged to be due for any brokerage or finder’s fee or agent’s commission or other payment in connection with this Agreement to be due by or through the Buyer as a result of the action of the Buyer or its officers, employees or agents.

7.10 Subrogation. Upon making an indemnity payment pursuant to this Agreement, the Indemnifying Party will, with the prior written consent of the Indemnified Party, such consent not to be unreasonably withheld, to the extent of such payment, be subrogated to all rights of the Indemnified Party against any third party in respect of the damages to which the payment related. Without limiting the generality of any other provision hereof and subject to the foregoing sentence, each such Indemnified Party and Indemnifying Party will duly execute upon request all instruments reasonably necessary to evidence and perfect the above described subrogation rights.

7.11 No Double Recovery; Use of Insurance. Notwithstanding anything herein to the contrary, no Party shall be entitled to indemnification or reimbursement under any provision of this Agreement for any amount to the extent such Party or its Affiliate has been indemnified or reimbursed for such amount under any other provision of this Agreement, the Exhibits or Disclosure Letter attached hereto, or any document executed in connection with this Agreement, by any insurance proceeds or under any insurance policy, or otherwise. To the extent that any Damages are covered by insurance, each Party hereto shall use its commercially reasonable efforts to collect any such amounts from such insurer. If a Party is reimbursed for such amount after receiving indemnification or reimbursement under this Agreement, the Party receiving reimbursement shall pay the amount reimbursed (up to the amount of indemnification received) to the other Party.

7.12 Treatment of Indemnity Payments Between the Parties. Unless otherwise required by applicable law, all indemnification payments shall constitute adjustments to the Purchase Price for all Tax purposes, and no Party shall take any position inconsistent with such characterization.

If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is invalid or unenforceable, the Parties agree that the court making the determination of invalidity or unenforceability shall have the power to reduce the scope, duration, or area of the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified after the expiration of the time within which the judgment may be appealed, provided that this Agreement shall not then substantially deprive either Party of the bargained-for performance of the other Party.

8.11 Expenses. Except as set forth in the next sentence, the legal and accounting obligations incurred to consummate the transaction on behalf of the Company shall be paid by the Company or the Company Stockholder as set forth in the Flow of Funds Memorandum. The Buyer (and not the Company or Company Stockholder) has and will pay the fees, expenses and disbursements of the Company and the Company Stockholder and each of their financial advisers, accountants and counsel incurred in connection with the subject matter of this Agreement as set forth in the Flow of Funds Memorandum, not to exceed Two Million Dollars ($2,000,000) (“Closing Fees and Expenses”). The Buyer has and will pay the fees, expenses and disbursements of the Buyer and each of its agents, representatives, financial advisers, accountants and counsel incurred in connection with the subject matter of this Agreement.

8.12 Exclusive Remedies. The remedies provided for in this Agreement shall be the sole and exclusive remedies of the Parties and their respective officers, directors, employees, Affiliates, agents, representatives, successors and assigns for any breach of or inaccuracy in any representation, warranty or covenant contained in this Agreement or any document delivered at Closing; provided, however, that nothing herein is intended to waive any claims for fraud or willful misconduct or waive any equitable remedies to which a Party may be entitled.

8.13 Employment Agreements; Confidentiality Agreements. The noncompetition and confidentiality provisions of the Employment Agreement and Agreements Concerning Confidential Information and Other Property constitute a material part of the purchase and sale transaction contemplated by this Agreement and are supported by adequate consideration. Notwithstanding the foregoing, and any other provisions of this Agreement to the contrary, the obligations of the individual parties under each such agreement shall not constitute an obligation of any other Party to this Agreement, and a breach of any such obligation shall not give rise to any claim for indemnification or recovery of Damages under this Agreement.

8.14 Specific Performance; Remedies. Each Party hereto acknowledges that the other Parties will be irreparably harmed and that there will be no adequate remedy at law for any violation by any of them of any of the covenants or agreements contained in this Agreement, including without limitation, the noncompetition provisions referenced in Section 8.13. It is accordingly agreed that, in addition to any other remedies that may be available upon the breach of any such covenants or agreements, each Party hereto shall have the right to obtain injunctive relief to restrain a breach or threatened breach of, or otherwise to obtain specific performance of, the covenants and agreements contained in this Agreement.

8.15 Construction. The Parties agree that they have been represented by counsel during the negotiation, preparation and execution of this Agreement and, therefore, waive the application of any law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the Party drafting such agreement or document. Any reference to any federal, state, local, or foreign statute or law shall be deemed also to refer to all rules and regulations promulgated thereunder, unless the context requires otherwise.

8.16 Incorporation of Exhibits and Schedules. The Exhibits and Disclosure Letter identified in this Agreement are incorporated herein by reference and made a part hereof.

8.17 Survival of Representations, Warranties and Covenants. The representations and warranties of the Parties hereto contained in this Agreement or in any exhibit, certificate, letter, or other writing delivered pursuant hereto or in connection herewith shall survive the Closing and will remain in effect until one year from the Closing, except (i) as to matters as to which a Party has delivered a General Escrow Claim Notice, an A/R Escrow Claim Notice or a Contract Escrow Claim prior to the expiration of the Escrow Period, which matters shall survive the expiration of such Escrow Period until such claim for Damages is finally resolved and any obligations with respect thereto are fully satisfied in accordance with this Agreement; and (ii) for the representatives and warranties set forth in Section 3.2 which will survive indefinitely and those set forth in Section 3.26 will survive until the expiration of the applicable statutes of limitations. Except as otherwise provided herein, the covenants of the Parties will survive the Closing and expire in accordance with their terms or the applicable statutes of limitations, whichever is earlier.
